ACETYLENE-GAS GENERATOR.

v citizen of the United States, residing at Pueblo, in the county of Pueblo and State of Colorado, have invented certain new and useful Improvements inAcet lene-Gas Generators; and I do hereby dec are the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is an acetylene gas generator and. relates more particularly to alamp of that type adapted to be used by miners.

An object of the invention is to provide a lamp having multiple carbid reservoirs so arranged that when the carb1d in one reser voir has become exhausted, the other reservoir may be employed while renewing the exhausted reservoir, thereby permitting the lamp to be burned continuously.

A further aim of the invention is to reduce to a minimum the danger of explosion of the lam through overproduction of gas providing ar escape of excess gas through the air supply tubes.

A further purpose of the invention 18 to simplify the construction of the device and to provide a lamp which Wlll be of few parts, durable, inexpensive to manufacture, and efiicient in operation.

Further objects and advanta es of the invention will become apparent rom the following detailed description taken in connection with the accompanying drawin While a preferred embodiment of t e invention is illustrated in the drawings, it is to be understood that the disclosure therein made is for the pur ose of illustration and not as defining the imits of the invention.

Figure 1 is a rear elevation of the lamp. Fig.2isa vertical sectional view through the lamp. Fig. 3 is a transverse section through the water reservoir disclosing the gas and water communications with the carbid reservoir. Fig. 4 is an enlarged detail view of the water tube and control valve.

In the embodiment of the invention herein illustrated, ashell is provided which forms a water reservoir 10. This shell may Specification of Letters Patent.

be of any preferred material and form, and is shown provided with threaded extensions 11 at the top and bottom thereof. The water reservoir shell, 10, is closed at each end by suitable plates 12, which may be of any appropriate shape to facilitate the How of water from the water reservoir. The water reservoir chamber may be filled through a ort 13, which may be closed by an i: suitab e means.

he end walls 12 may be suitably perforated at 14 to permit water to fiow from the water reservoir, and may have another perforation through which extends a gas conductor 15. Two of these as conductors are illustrated, one leading rom each end 12 of the water reservoir shell, and extended toward each other where the conductors are bent to extend outwardly, as at 16, beyond the wall of the shell to conduct the gas to a suitable burner tip within a reflector 17.

Communicatingwith the water aperture 14 of each end wall 12 is a water tube, 18, which is shown provided with an angular member having an aperature 20 adapted to register with the water aperture 14 of the end wall 12. Within this angular section 19 there is positioned a piston 21, which is adapted to e advanced, by a threaded rod 22, to close the aperture 20. This rod 22 is shown extended beyond the wall of the shell and provided with a key 23 to facilitate rotation of the rod 22 to control the supply of water without dismantling the lamp.

The main section 18 of the water tube is adapted to extend into the carbid reservoir, and it is preferred to mount a cleaning wire 24 in this tube 18 to insure the free passage of water through the tube 18, and prevent the tube from becoming clog ed with carbid. This wire is preferably threaded at one end 25 to engage threads in the tube 18 for the, urpose of retaining the w re in position. t the other end 26, the wire may be provided with a head to facilitate t e rotation thereof. If desired, the threaded end 25 may be enlarged to serve as a cleaner member to scrape out the tube 18. This tube 18, may also be provided with a vent aperture 27, intermediate the ends thereof,to permit excess "as to escape through the water tube into tie water reservoir chamber.

Within the water reservoir chamber 10 there .is positioned ,an air tube. Two of these .air' tube re shown in the drawings, one, .28, having an angular portion 28" extending through the wall of the shell 10 to communicate with the exterior of the lamp, and having its other end 28 terminating near the upper end wall 12. The other tube 29is reverscly mounted with its air admission end '29"positiened at that end of the reservoir shell which is shown as the top in the drawings, and with its other end opening near the bottom end plate 12. 'lhcse tubes .28, 2t) operate alternately to admit air to the water reservoir, and also to serve as means to permit the-escape of excess gas from the gas reservoir and from the water reservoir, thereby preventing 1njurv to the lamp.

he carbid reservoirs are in the form of cups 30, which are provided with a threaded contracted end 31 adapted to engage the threaded extensions 11 of the water reservoir shell 10. The carbid reservoirs are interchangeable and are adapted to be used alternately, thereb permitting the removal of one reservoir rom the shell to fill the same while the continued use of the lamp may be effected from the other reservoir.

Each reservoir 30 may be provided with any suitable means to support and retain a fiber or felt filter pad 32, and if desired, its wire mesh sup ort 33.

At the rear of t to lamp, there is provided a suitable device to reversibly support the lamp.- This means is shown as a double ended hook, the end 34 being shown positioned at right angles to the end 35. The body of the hook is pivotally supported in brackets 35, whereby one end, such as 34 may be used to engage means to support the lamp, while the other end'35 will operate to hold the lamp against movement in one direction on the hook.

In operation, water is placed in the water reservoir 10 through port 18, and is ormitted to flow from the water chamber into the carbid reservoir 30 at the bottom of the lamp, through the water tube 18, 21. Gas formed in the carbid reservoir, will pass through the filter 32, out through the gas conductor 15 to the burner tip, and should more gas be generated than is consumed, the surplus gas will find its way from the carbid reservoir into the water reservoir through the-water tube 18. For this purpose one or more'vents'27 may be employed in the tube 18. The gas, on entering, the water reservoir, will be conducted to the top thereof and may-escape through air tube 28 or 29. When the carbid in the lower reservoir shall have become exhausted, the water'valve to the lower carbid reservoir may be closed by means of the key 23, and the valve to the upper reservoir opened, whereupon the lamp may be reversed to bring the other reservoir into operation, while refilling the exhausted reservoir. r

Having thus described my invention,what I claim as new and desire to secure by Letters Patent is:

1. An acetylene gas enerator including a water reservoir, a carbid reservoir, and a water tube to connect with said reservoirs, said tube having a water port registering with a port of the water reservoir, a member of the tube being positioned out of alinement with said ports, a threaded seat in said tube member, a core element having an enlarged threaded end to engage said seat when in its inoperative position, the threaded end of said core element operating, when disconnected from its seat and moved longitudinally in the tube member, to free the tube from obstructions.

2. An acetylene gas generator including a water reservoir, :1 carbid reservoir, and a water tube to connect said reservoirs, said tubes having a water port opening into a water port of the water reservoir, a member of the tube being positioned out of alinement with said arts, and having a threaded seat at one end thereof beyond the water passa e, a core element havin an enlarged threaded end-slightly less in diameter than the internal diameter of said tube and adapted toengage said threaded seat, said threaded end operating to free the tube from obstructions when the core element is moved longitudinally in the tube member.
